A heat shield and a heat shield assembly

摘要

A heat shield (10) comprises a metal sheet (12) with a thermal sprayed layer of ceramic material (14) thereon, the sheet (12) defining an array of dimples (16) and/or pimples (18) such that any notional plane intersecting the coated surface of the metal sheet (12) creates a notional line of intersection which intersects at least some dimples (16) and/or pimples (18).
